Microsoft, Sony Remain Upbeat About Holiday Sales

Yahoo: "Sales of both the Microsoft Xbox 360 line and the Sony PlayStation 3 lag well behind the popular Nintendo Wii. The Nintendo PlayStation DS also enjoys a solid lead over Sony's PlayStation Portable, although that trend has slowed or even reversed recently in Japan.

Nintendo is not at the Tokyo Game Show -- an event it routinely skips. Its two rivals, however, are taking full advantage of the opportunity to showcase new offerings."
